A small one-quarter mile segment of an ancient Native American trail used by Lewis and Clark in 1806 is still visible from Highway 12. This Native American trail, was a travois road, which is parallel ruts created by the repeated travel of dogs and horses dragging two long poles attached to either side along the ground. This road originally extended from the confluence of the Walla Walla and Columbia Rivers to the confluence of the Snake and Clearwater Rivers, providing access to fishing grounds for the Nez Perce, Walla Walla and Cayuse tribes.
